I am trying to help a teacher friend with teaching her kids to design 3D objects using TC. I'm experienced in Autocad and Revit, not so much with 3D printers. She's tried to turn the recent flooding in Houston into a class project to design and 3D print house models that survive flooding. The kids have come up with several creative drawings, but the whole experiment is at risk of being a failure because the designs won't print or often wont compile a usable STL print file. I've tried creating a simple drawing to test, but when I email it to her, she can't even save the file. We both need comprehensive instruction, but most of the stuff on YouTube and the skimpy TinkerCad instruction is of little or no help. Advice to save the whole design and print in 3D idea?
